Undefined symbols for architecture x86_64: "_ompi_buffer_detach_f08", referenced from

Dear all,

I built Openmpi with ifort successfully.

I am trying to use Openmpi with ifort but got the following error,

Undefined symbols for architecture x86_64:

"_ompi_buffer_detach_f08", referenced from:

System: macOS Catalina

openmpi-4.0.5.tar.gz

$ ./configure --prefix=/usr/local/share/

$ make all install

Intel fortran

m_fcompxe_2020.2.899.dmg

Any idea about how to fix this?

Best regards,

Sean

you might need to read the OpenMPI configure options. I believe you need to set the Fortran compiler to Intel. Default is normally gfortran FC=ifort for example.

Or search for how to build OpenMPI for Intel Fortran.

Thanks.

It was configured with ifort because GCC was not installed in the macOS,

that is why I didn't specify the FC in the configuration file.

This was identified to be an issue of Intel Fortran as can be seen from the following discussion.

I don't know if this issue has been reported to Intel Fortran development team.

I had the same problem and here's how I made openmpi work for macOS 10.15.7, Xcode 11.7, intel parallel studio xe 19.1.3.301 and openMPI 4.0.5. Configure openmpi 4.0.5:

./configure --prefix=/opt/openmpi CC=icc CXX=icc F77=ifort FC=ifort  lt_prog_compiler_wl_FC=-Wl,

Then when that finishes, open up the libtool generated by configure in your text editor and change lines 11837 to 11841 to

# Additional compiler flags for building library objects.
pic_flag=" -fno-common -fPIC"

# How to pass a linker flag through the compiler.
wl="-Wl,"

Then make and install openmpi:

sudo make all install

And then another tedious compiler and system upgrade day comes to a close...

Also, I after upgrading the PSXE today, I had the zsh bug with

source /opt/intel/bin/compilervars.sh intel64

where it complained

remove_duplicate_paths:4: bad substitution
remove_duplicate_paths:4: bad substitution
...

and this fix worked for that.
